Answer:
yes it is.
Step-by-step explanation:
Answer:
χ²R = 8.643
χ²L = 42.796
0.20 < σ < 0.45
Step-by-step explanation:
Given :
Sample size, n = 23
The degree of freedom, df = n - 1 = 23 - 1 = 22
At α - level = 99%
For χ²R ; 1 - (1 - 0.99)/2= 0.995 ; df = 22 ; χ²R = 8.643
For χ²L ; (1 - 0.99)/2 = 0.005 ; df = 22 ; χ²L = 42.796
The confidence interval of σ ;
s * √[(n-1)/χ²L] < σ < s * √[(n-1)/χ²R)]
0.28 * √(22/42.796) < σ < 0.28 * √(22/8.643)
0.2008 < σ < 0.4467
0.20 < σ < 0.45

Answer:
110%
Step-by-step explanation:
Each stripe is 1/10 of a whole, so represents 100%/10 = 10% of the whole.
There are 11 shaded stripes, representing 11×10% = 110%.
Answer:
Everyone will get 
amount of cakes.
Step-by-step explanation:
Given:
Number of Cakes Josh buys = 35
Number of Students Josh wants to share = 86
Josh need to share cakes with fifth grade students.
We need to find the fraction of cakes everyone will get.
So to find the the fraction of cakes everyone will get can be calculated by dividing Number of Cakes Josh buys with Number of students he want to share with.
Amount of cakes Every one will get = 
Now Substituting the values we get;
Amount of cakes Every one will get =
Hence Everyone will get amount of cakes.
Answer:
x=-25
Step-by-step explanation:
Inverse variation
xy =k
We know x and y
20*5 =k
100 =k
So the formula is
x y = 100
We know y = -4
x (-4) = 100
Divide each side by -4
-4x/-4 = 100/-4
x = -25
